I am new to Linux and QCAD. reading the help files it states that QCAD by default saves in 2013 DWG or DXF format, but it does not. I did opt out of the two trial add ons because I am using it on a trial basis, to see if it will fulfill my needs. I swear that before canceling these trial add ons I test opened a AutoCAD LT 2013 file and after I could not. Do you force people to purchase to look and newer than 2000 file available in the free version? How can I get 2013 functionality back? DO I need to uninstall and reinstall?
